Hi
i am quite stuck with this problem and could really need help:
my Situation right now:
- concatenated 121 files with each 21000 measurments each, to a torque channel ( MyR ) and a rpm channel( Rotspd ) via skript
- created a numerik time channel ( time ) starting a 0-72600s, with 2541000 number values based on the number of files and measurements.
- choose FFT (One Time Signal), Time channel: time, Signal channel: MyR, Window type: Retancle, FFT: Amplitudepeak, Average Amplitude: None, Third/Oktave: No
( PIC: 1-3 )
my Problem:
after applying the FFT, i displayed the results and :
-the original measurment values&peaks do not correspond to the resulting amplitude peaks
i am using:
DIAdem 2015
15.0. (64 Bit)
How do i achieve the output values regarding peaks in my FFT output ?
Is there a better signal analyse funktion in Diadem besides FFT which results in Frequency(X) and Amplitude(Y) ?
Kind regards and big thanks in advance
